To rzv/i ii /mm if may concern:

Be it known that we, Janus (woman and ALEXANDER bvrunnin xn, citizens of the- United fitates. residing at Bullalo, 1n the county of invented a new and useful Improvement in Fountainl irushes; oi which the following is a spccilicat ion.

Thisinvention relates to a brush-in which the liquid is supplied from al ountain connected "with the brush.

The object of our invention is the production ol :1 brush of this character which is more particularly designed for applying liquid polish to stoves: and the invention to that end consists, essentially, in so constructing the brush that the same can be attached directly to the cans in which the liquid polish is marketed and to provide a valve mechanism which shuts oil' the connection between the can and the brush when turned either up or downdvut permits the liquid polish-to flow from the can to the brush in the act of moving the same while in use.

In the accompanying drawings, Figure l is a vertica section showing our improved brush appl to n liquid-supply can or reservoir. Fig. .2 is a. horizontalsection in line 2 Fig. 1. 4

Similar letters of reference ind' ate corresponding parts in both figures.

A represents the brush whereby the liquid spread over the surface to be coated. 'lhis brush may be variously constructed, but con sists, preferably, oi a wood stock a, carrying the bristles b, and a. sheet-metal jacket editting over the stock. Extending from the upper to the lower side of the stock and jacket in the central parts thereof is a conduit or passage (1, through which the liquid. to be spread is conducted to the bristles of the brush. This liquid is supplied from a can, fountain, or reservoir E, which has its outlet connected with the delivery conduit or passage (5. As shown in the dawings, this con constructed of sheet metal and is detachably connected with the brush by means of an internally-threaded sheet-metal socket F, se cured centrally to the top of the brush-jacket by soldering or otherwise and receiving the externally-threaded neck G of the supplycan.

For the purpose 0t interrupting communication between the supply-can and the brush Erie and State of New York, have i or upimrdly, but establishin c communioation between the same when the brush is in usc,a double-acting valve mechanism is provided, which is preferably construclml as follows:

ll represents a short circular casing or thimble mounted on the bottom of the s cket 1* and forming therewith a valve-chumbcr 71 This thimble, if desired, may be permanently secured to the bottom of the socket by soldering or otherwisc; but the same is preferably made detachable for convenience in cleaning by forming an external annular flange It on the lower end oi the thimble and securing the same in place by engaging its periphery friction-ally with the bore of the socket and also by clamping the same between the bottom of the socket l and the inner end ofthe neck G, as shown in l ig. 1. her is a valve or stopper 1, having preferably the form ol a ball or sphere. At its opposite ends the chamber is provided with an inletopening surrounded on its innerside by anannular valve-seat j and an outlet-opening surrounded on its inner side byan annular valveseat 7c. The inlet-openiru: and valve-seat are formed on the top of the \'alve-cliambcr,

1 and the outlet-opening and valve-scat Ir are lormed on the bottomof thcsocket, assuming the brush to be facing downwardly.

The vnlvc-chambcr is preferably of such diameter or width that no shoulders are formed around tho valve-seats .on which the valve can lodge, and the walls of the chamber also taper or converge toward the valve-seats.

l By this means the valve is permitted to move laterally out of alincment with the seats for uncoverin the same, while they brush is moved by the hand in the act of brushing, thereby permitting the liquid to [low from the can to the brush; butwhcii the brushing movement ccascs or the can and brush are inverted the ball-valve is guided to either scatv and prevents the escape of the liquid or the admission of air.

For the purpose of forming a liquid-tight joint between the can and the valve-casing the latter is made to taper toward its inletopcning and the neck ol'thc can is provided at its outer end with an inwardly-projecting llungc Z, which bears against the base ol the tapering part oi" the valve-casing, as shown in Fig. 1. By this means these parts engage each other with a wedge-like action when the Within the valvecham- .substitution of an empty liquid-polish pocket can and brush are screwed together, producing a joint between the same which is not liable to leak.

In the use of this brush the same is screwed with its socket onto the neck of the can while the latter-is upright. Then the parts are in this position, the valve is seated over the inlet-opening, thereby excluding the atmosphere and dust and preventing evaporation and deterioration of the contents of the can. Upon turnin the can upside down the ball-valve seats itse f over the outlet-opening of the casing, thereby preventing the escape of the liquid from the can in this position of the parts. As the brush while projecting downwardly is moved back and forth laterally over the surface to be coated the ballvalve rolls off from the outlet-opening and alternately from one side thereof to the other, thereby permitting the liquid to flow intermittently from the can through the valvecasing anddelivery-passage to the bristles of thebrush, which latter spread the same over the surface to be coated as the liquid issues from the delivery-passage. The instant the lateral movement of the brush ceases the ball seats itself over the outlet-opening and ar rests the further discharge of liquid. It will thus be noted that the supply of liquid continues so lon as the same is consumed by the motion 0 the brush; but when this motion, and consequently the consumption of the liquid, stops the supply of l quid is also automatically arrested.

Our improvement is especially useful for applyin liquid polish to stoves. This polish is usually put up for the market in small cans, which can be screwed directly into the sockets of the brushes and serve as handles for manipulating the latter. All liability of soiling the hands is thus avoid ed,beeause the by a filled one may be efi'ected without danger of getting the liquid on the hands.

We claim as our inventioni 1. A fountain-brush provided witha'valve chamber having an inlet and an outlet, and a'single movable stopper 0 erating to close either said inlet or said out et, substantially as set forth.

2. A fountain-brush provided with a valvechamber having an inlet and an outlet at opposite ends, and a ball-valve arranged in said 1 emcee chamber and adapted to close eithersaid inlet or said outlet, substantially as set forth.

3. A fountain-brush comprising a stock having a delivery-conduit, a socket for receiving the neck of a fountain secured to said stock and having an outlet-opening which communicates with said i-lelivery-conduit, a thimble bearing at one end against said socket and having an inlet-opening at its op' posite end, said thimble and socket forming a valve-chamber, and a valve arranged in said chamber and adapted to close either of said openings, substantially as set forth.

4. The combination of a brush provided in its stock with a liquid delivery conduit, a screw-socket secured to said stock and having an outlet-opening communicating with said conduit, a thimble having an external flange fitting the bore of said socket and provided with an inletopening, said thimble and socket together forming a valvechamber, a ball -valve arranged in said chamber and adapted to close either said inlet or said outlet opening, and a liquid-supply havin a threaded neck which screws into said. soc et and bears against said flange of the thimble,

substantially as set forth. a 5. The combination of a brush provided in its stock with a liquid delivery conduit, a

screw-socket secured to said stock and having an outlet-openmg communicating with said conduit, a thimble having an external.

flange at one end which rests on the bottom of said socket and tapering toward its Opposit e end and is provided at the last-mentioned end with an inletopening, said thimble and socket together forming a valve-chamber, a liquid supply can or fountain having a threaded neck which screws into said socket and an internal flange in its neck which engages with the flange and the base of said thimble, and a ball-valve arranged in said chamber and adapted to close said inlet-epen- 1 ing or, said outlet-opening, substantially as set forth.
